There are a lot of different issues that you can encounter on your PC and a big portion of them have to do with malicious software that can harm them or even turn them against their user.

In response to the new threat, we have created this article, in which our main goal is to inform our readers about what Js/injector.a is capable of, how it can potentially be detected and what precautions must be taken in order to avoid having your PC infected by the nasty malware. Certainly, many of you who are currently reading this have come here seeking a way to deal with the virus, since it has already infected your system. For that, we have an instruction manual, in which we have combined a number of different Trojan horse removal methods that should be able to help you handle the threat and clean your machine of the malicious Js/injector.a.

Spotting the infection

The best way to detect a Trojan horse infection certainly is by having dependable, high-quality security software on your PC. However, even the best antivirus programs have their flaws and shortcomings and there’s always the possibility that a virus can go under their radar. This is why users need to have a general idea of what the potential symptoms caused by Trojan horse viruses are. Unfortunately, a major issue with manually detecting a Trojan is that in many of the instances the virus will show no signs of infection. Also, many symptoms that are commonly associated with Trojans can be caused by a variety of other software (or hardware) problems. Still, knowing what you can potentially expect is a good way of increasing the overall protection levels of your machine.

  • Some Trojans are known to cause BSOD (Blue Screen of Death) crashes. If your machine has started experiencing those, this might mean that it has been attacked by Js/injector.a.
  • Another possible symptom is if any of your files or folder begin to disappear or are getting moved from one place to another. If this happens, immediately go for our guide down below the article and complete all the steps.
  • Another, though less common, possibility is that your browser gets flooded with obnoxious and shady ads, pop-ups banners, etc. Usually, this symptom is more typical for programs of the Adware or the Browser Hijacker type, but it can still be caused by a Trojan infection.
  • If your PC becomes sluggish and you notice sudden and unexpected RAM or CPU spikes that do not seem to be caused by a specific program then there’s a high chance that your machine has either been infected by a Trojan or has some other unwanted and potentially dangerous application that has been installed on it. In such cases, it is a good idea to check the Task Manager and see which process is causing the increased system resource consumption since this is likely a process ran by the virus.

What can Trojans do to your PC?

As was stated in the beginning of the article, viruses like Js/injector.a can have a number of different uses. In this paragraph, we will try to give you a general idea of what most Trojans are capable of once they infect the user’s computer.

  • They can spy on you through different methods. Among the most common espionage techniques are keystroke logging, spying on the PC screen and also using the web camera to look directly at the user.
  • Through the aforementioned espionage methods, the hackers are able to acquire valuable and/or sensitive data about their victim and later blackmail them or steal money from their bank accounts if the password and username to the account have been obtained.
  • Lately, many Ransomware viruses are used in conjunction with Trojan horses. The latter is used to provide the Ransomware with a gateway to the PC’s system serving as a backdoor. That way, the machine can be infected with Ransomware even if the user did not do anything that would compromise the computer’s security.
  • Additionally, a lot of Trojan horses are used to directly attack the system files of the user’s computer. The files can be corrupted or outright deleted leading to all sorts of problems with the computer such as crashes, general system instability, etc. In some cases, the PC might not even be able to start.

PC maintenance and protection

Last but not least, you will need to learn what precautions you must take in order to keep malicious Trojans like Js/injector.a away from your machine. For maximum protection, be sure to memorize and put into use all of the following tips and guidelines.

  • Be very careful when downloading new software. First of all, never allow new files to be automatically downloaded without your browser first asking you for permission. Secondly, only use reliable and trusted download sources.
  • DO NOT click on any shady and suspicious-looking online banners and adverts and avoid sites that might contain them.
  • Always make sure that new e-mails are not some sort of spam prior to opening them. If a new letter seems like it might be spam, be sure to directly delete it.
  • Never leave your machine without a reliable and fully updated antivirus program. Also, make sure that your Windows is getting the latest updates from the official Microsoft website as soon as they are released.
